Specification of Letters Patent.

Patented sept. 19, 1916.

Application filed March 15, 1912. Serial No. 684,074'.

To all whom t may concern Be it known that we, RICHARD L. LLOYD andROBERT D. SIMPSON, citizens of the United States, residing,respectively, at

Portsmouth and Columbus, in the counties,

respectively, of Scioto and Franklin, State of Ohio, have inventedcertain new and useful Improvements in Machines for MarkingButtonhole-Flies, of which the following is a specification.

This invention relates to the marking of shoe uppers to indicate theposition on the upper where certainy operations are to take place, suchas the making of buttonholes, attachment of buttons, etc. l

It has been the practice to mark the loca-- tions of buttons andbuttonholes on the shoe upper material by piercing or indenting thematerial of the upper with a marking tool or a series of marking devicesforming part of a marking machine. In certain upper materials, such assoft lea-ther, cloth, canvas, etc., vthe puncture or indentationsubsequently closes up or disappears so that when the time arrives toutilize the indication mark it is not discernible. It` has also been thepractice to mark upper materials with inked markers but the ink has atendencyy to spread particularlyv in cloth and canvas, and the exactlocation of the mark is not easily ascertained. Furthermore theappearance. of the upper is injured by the spreading ink or colored dye.When chalk is used the mark becomes smeared and the indication is soblurred as to be useless.

A conspicuous feature of our invention consists in a machine forAmarking vshoe up-' per materials provided with marking means arranged toplace a dry indelible indication upon the upper material which willalways be discernible by contrast with the adjacent unmarked portions ofthe material. Incidentally the machine involves the application of anovel method of marking uppers. 7e accomplish the result stated byemploying heated markers to cauterize the surface of the material.Preferably these markers are electrically heated.

Another feature of the invention consists in a structure Vproviding twoseries of cauteriZi-ng markers with means for causing a heating electriccircuit to pass through either series. Such al construction permits themarking of either face of the material.

A further feature resides in anovel construction of electrically heatedmarkers.

Another feature of the invention consists inl two series of alinedcauterizing marker elements with means for simultaneously moving bothseries of elements to vary their relative spacing, and with means forheating either series of marker elements.

A still further feature of the invention consists in the meansforadjusting a series of markers longitudinally of a guiding element soas to determinately vary the spacing between the markers. 'y

These and other features and advantages will be more fully apparent froma reading of the following specification in connection with theaccompanying drawings, in which- Figure l is a. front elevation ofamarking machine constructed in accordance with a preferable embodimentof the! invention; Fig. 2 is atransverse, vertical lsection of themachine sho-wn in Fig. l; Fig. y3 is a top plan view of the machineshown inl Figs. l and 2, the cover beingv removedv to ldisclose theinterior arrangement; Figs. 4; and 5 are views in top planand frontelevation of the knee operated lever element for controlling the spacingofthe marking elements; Fig. Gis a plan view of the yoke by means ofwhich the lower series of marking elements are moved to effect markingof the work; Figs. 7 and 8 are views in side and front elevationrespectively of one of the movable blocks carrying the upper and lowermarking members, the block shown in the present instance being one ofthe terminal blocks of the series; Fig. 9 is a view in front elevationof the other terminal block of the series,

including the switch for directing the heating current to the upper orlower series of markers; and Fig. 1() is a top plan view of the partsshown in Fig. 9; and Figs. 11 and 12 are views in top plan and sideelevation respectively of one of the links connecting the markercarrying blocks with the spacing lever; Fig. 13 is a diagrammatic viewillustrating the current distribution and control; and Fig. 14 is adetail, in section, of the end gage used to position the end of the workrelatively to the markers.

The machine comprises a suitable support including a tubular standard lwhose upper end is secured to and supports a base 2, upon which ismounted a rear wall 8 and side walls h1 forming a housing- .for theoperating parts of the machine. A hinged cover is preferably providedfor the housing. At the front edge of the base a work supporting boardor plate is secured and is formed to provide its inner edge with a curvecor responding substantially with the curve of the buttonhole Hy of ashoe upper. From the curved edge of the work support rearwardly, thebase 2 is slotted, as shown at G, the rear edge of the slot having anupstand- .ing flange or guide plate 7. This guide plate is intended toreceive and guide a series of marker carrying blocks or marker units formovement longitudinally of the guide to vary their spacing. These unitsor blocks, indicated at S, have their lower rear faces inwardly offsetand provided with vertical bifurcating slots 9 therein extendingupwardly from the base of the block. rlhese slots are of suiiicientwidth to receive the guide flange or plate 7 therein, so that the blocksare supported on the guide plate by means of these slots. The front faceof each of the blocks, at a point between its upper and lower end, isrecessed inwardly, as at 9 to provide space for the insertion of theedge of the fly so that the work may be positioned between spaced upperand lower marking elements mounted on the block above and below thisbifurcation. The outer face of each of the blocks above and below therecess 9a is provided with insulating strips or plates 10 and 12. Theupper plate 10 carries an insulated stud 11 and the lower plate aninsulated stud 15 to which the marker elements are secured, as laterexplained. The lower insulating` plate 12 is provided with alongitudinal slot 1-1 therein extending vertically of the block and pins13 secured to the block S extend through this slot and guide the lowerplate 12 for vertical movement toward the upper plate 1() which is.rigidly secured by suitable means to the outer tace of the block. Thebases of the lower insulating plates 12 carry resilient hook elements 16adapted to clasp the edge of a frame 17 positioned below the bed 2 andpivoted at its rear end at 19 to the bed of the machine. The engagededge of the bar 17 of this frame is formed on a curve corresponding tothe curve of the slot 6 and curved edge of the work support 5. It isarranged to be moved upwardly to move the lower insulated blocks l2upwardly, by nieans of a pivoted link 20 attached at its lower end to abar 1S of the frame and pivoted at its upper end to a lever 21. rlhislever is t'ulcrumed at 22 upon the base of the machine and has at itsforward end a pivoted rod 21L extending downwardly through the tubularstandard 1 with its lower end in turn pivoted to a treadle 21b having alateral oliset, (Fig. 1) arranged to be engaged by the foot of theoperator. Movement of the treadle downwardly serves to pull the frame 17upwardly through link 20 so that the series of lower insulated plates 12are moved upwardly toward the upper series. At the same time, the rearend of lever 21 is arranged to close an electric switch in a circuitwhich includes electrically heated markers carried by the upper andlower series of insulated blocks 10 and 12. To this end, a projectingbar switch 23 is carried by the rear end of lever 21 with suitableintermediary insulation and is arranged to engage and bridge spacedswitch contacts 21 when so moved. break in the circuit has been closedthrough a manually operated selective switch, the current will passthrough either the upper or lower set of marker elements carried by theinsulated series 10 and 12. The marker elements are formed by a singlelength of flexible, conducting ribbon 25, which extends along the upperseries of plates l0 and is provided with V-shaped portions, the lowerends of which engage the insulated studs 11, this ribbon at one end ofthe series of upper plates 12 being then bent downwardly and extendedalong the line of lower plates 12 in a similar manner with inverted V-shaped portions or loops embracing the insulated studs 15 of the lowerseries of plates. The extremities of these loops or V-shaped portionsare in the form of sharp bends 2G which proj eet above the edges of theinward recesses 9a of the blocks. The terminals of the conducting ribbon25 opposite the closed end of the ribbon or at the left end of theseries shown in Fig. 3 are connected with switch jaws 27, 28. Adjacentthese switch jaws is located a manually controlled selective switch inthe form of a pivoted switch blade 29 having an operating handle 30 andarranged in line with switch jaws 27, 28. By connecting the blade 29with one of the jaws 27 or 28, the current maybe caused to pass througheither the lVhen a second upper or lower series of marking bends 26 ofthe ribbon 25. The ribbon itself being fiexible, provides a series oflongitudinally extensible and contractible cauterizing portions as wellas two series of opposed cauterizing portions relatively movable. Theelectric circuit for effecting this heating is best seen in Fig. 13 inwhich a wire 35 leading from one side of a source of current isconnected to one of the spaced contacts 24 of the bridge switch. Theother contact of the switch is connected with a resistance coil 37, theopposite end of this coil being in turn connected to a rheostat 38, thecurrent passing through the rheostat and out by a wire 31 to the knifeswitch 29, thence through either the upper or lower series of markingbends 26 of the ribbon 25, depending upon the connection of the switchblade 29, to the other side of the source of current. A wire 34 isconnected to the closed end of the ribbon 25 and leads from saidribbon-to the other side of the current source.

1t will be understood that in marking the buttonhole fly, it is placedupon the work support 5 with the edge of the fly extending into therecess 9a of the blocks 8 and positioned by eye so that the edge of thefly is spaced from the markers substantially uniformly and for thedesired distance. The end of the fly is positioned at the appropriatedistance from the first marking element of the series by means of an endgage in the form of a swinging arm 39, whose end forms a stop againstwhich the end of the fly rests. This end gage may be swung to vary thedistance of the first mark from the end of the fly by means of a thumbbolt 39a. The number of buttonholes to be marked as well as the relativespacing between the buttonholes will vary in different shoes andconsequently, before the treadle 21b is operated to close the circuitand lift the lower series of markers, the markers themselves should beproperly adjusted. These markers will bear certain indications, such asnumbers, by means of which the operator can readily utilize the desirednumber of marking elements. To space properly the selected number ofelements, the following mechanism is employed: Each of the series ofblocks 8 except the first one has its rear formed with a perforation orsocket 42. At the rear and right end of the base, as viewed in Fig. 3, aspacing lever 43 is fulcrumed on a vertically extending shaft 47. Thislever 43 is provided with a plurality of longitudinally extending andalined journaling apertures therein and a series of links in the form ofrods 40 are arranged to connect this adjusting lever with the successiveblocks 8. To this end the rods 40 are each bent to a particular form andat their forward ends are provided with depending portions 41 seated inthe sockets 42 of the blocks 8. At their rear ends these rods carrythreaded sleeves 44 having extensions 45 with depending pins 46 designedto journal in the successive apertures in the adjusting lever 43. Thethreaded sleeve 44 provides for adjustment of the length of the rods.The links 40 and the lever 43 are figured to provide a definite andascertained movement of the links 40 and of the blocks 8, connected totheir outer ends, so that when the adjusting lever is moved the links4() will slide the blocks longitudinally on the guide plates 7 and willspace the blocks equally at various points of movement of the adjustinglever 43. The spacing of the marking blocks occurs from one end of theseries and relative to an end block of the series which is fixed. InFig.' 3 of the drawings this end block is found at the extreme left handend of the series and is secured in desired position on the guide plate7 by means of a set screw 48. It is, of course, understood that there isno link 40 connected to this fixed marking member. Movement of the lever43, will, therefore, move the successive blocks from and toward eachother and from and toward the fixed end block to give the desiredspacing of the markers carried by the blocks. The adjusting movement ofthe lever is preferably limited by stop pins 49 and 50 (Fig. Adjustingmovement of the lever is effected by the operator through a rod 51co-axial with and depending from the shaft 47 which forms the axis aboutwhich the lever turns. This rod 51 has detachably secured to it the rearend of a bar 52. As seen in Fig. 4, the rear end of this bar is formedas a split socket or collar 53 with an operating handle 54 arranged toclamp the collar about the rod 51. The forward end of the bar 52 isprovided with an elongated slot 55 therein with a cross bar 56, which isdovetailed into the slotted portion of the bar 52 and has a wing nut 57for clamping the cross bar at various distances from the forward end ofthe bar 52. This adjustment enables the cross bar to be positionedaccording to the location of the knee of the operator which is to beinserted between the spaced rods 58 and 59 depending from the cross bar56 and adjustable on the cross bar by means of nuts 60 and 61. Movementof the operators knee will swing the bar 52, turning the rod 51 andshaft 47 to swing the adjusting lever 43. V

With the fly inserted between the properly spaced markers, the operatordepresses the treadle 21B, moving upwardly the lower set of insulatedblocks 12 with their marking points to engage the iy between the twoseries of marking points, the ribbon 25 being sutliciently ileXible topermit this movement. lVhen the knife switch 29 has been moved to closethe circuit through the lower series of marking points, the under faceof the ly will be cauterized to provide a series of dry indelible marksindicating the locations of the buttonholes. It' the upper series ofmarking points has been energized, these points will similarly mark theupper face of the fiy. The indication mark made by the eauterizing ofthe surface of the upper material is not only dry and indelible, butwill always be clearly discernable, whatever the nature o'l thematerials, because of the eifect of the cauterization upon the materialitself. The cauterization will always change the color of the canterizedspot either to a different shade so that the mark will be discernibleunder all conditions.

The novel method herein disclosed, which is characterized by the step ofcauterizing the surface of the material to form indicating marks, is notclaimed herein but forms the subject-matter of our divisionalapplication liled February 8, 1916, Ser. No. 76,940.
